I'm not sure why that is something to praise. > Again, this seems like you complaining that you don't yet have a penthouse when they're still pouring the concrete foundation. It's the other way around: cheap space flight is the penthouse of planetary colonization. The foundation is the ability to build a self-sufficient colony. Once we were able to colonize the least hospitable places on Earth, only then would it make sense to think about how we move this technology to Mars - 50 or 100 years from now, most likely. It's also worth noting that we have no reason to assume that a human population can even survive on Mars, as we have no idea if humans can live long term or even reproduce in Martian conditions (especially the very low gravity). Before even thinking about this colonization, we would actually have to establish whether it's possible for mammals to live long term and reproduce in low-G conditions. If it's not, there's a whole new world of technology we would have to discover before attempting it. SpaceX is to Mars colonization like buying your dream wedding dress not just before finding a boyfriend, but before even knowing if you're gay or straight. > Firstly, the incumbents are too large in that industry to compete with. You could say the same for the car industry itself. > Musk clearly likes cars. Humanity arguably needs electric cars. Musk combined a passion for cars with humanity's need. Fair enough.
